Overall a good product. There seemed to be a slight difference in thickness between the filters in each package. I would have preferred they all be the same but I would purchase again.

Rated 5.0 out of 5.0 by IronAvatar Does its intended job
I installed these throughout the house before tearing out old plaster-and-lath walls in my attic. They helped tremendously in removing the plaster dust from the air that escaped attic containment. Quality control is a bit off at the manufacturer though, as the filters vary in thickness within a package, but they still work. They have done a great job filtering out dust, candle soot, and especially cat hair (we have 3 cats). We now replace them every 3 months or as needed when they darken from particle collection. We have some registers and vents that are wider than the filters, but they still collect a noticeable amount of impurities even though there are gaps at the edges of these extra-wide vents

I use theses when initiating swamp coolers each spring. They catch the dust and dirt accumulated in the system over the winter.

This product a little bit thicker than other vent filters and may impede air flow slightly, but is extremely easy to use. Usually has to be cut to fit.

I bought this item trying to reduce dust in my house. The size of the filter in this package is too small vent in new houses. No effect in reducing airborn dusts after installed this vent filter.
